If you place a mouse in a maze for the rst time, the mouse will have no knowledge of how to exit the maze. It will scurry around taking random turns at junctions. It may encounter many dead ends before it nally happens upon the exit by pure chance. In this section we will develop a simple algorithm that relies on random chance to solve the maze. In the subsequent sections more complicated routines will be developed. This rst simple algorithm can be useful in indicating how we can proceed to more intelligent attempts. Additionally, the base program in this section will be used throughout the chapter with changes made only to the routines that need modi cation to improve the behavior of the robot.

14.1.1 THE PROGRAM The program of Fig. 14.1 allows the user to place the robot anywhere in a randomly generated line maze, but it has to be over a line. Also, the user is allowed to give the robot an initial heading, but this heading can only be north, south, east, or west. If the robot is placed where its front is not on a line the program will turn the robot to put its front on a line. After placing the robot the user then chooses a goal location. The location must be on a line, but it can be anywhere the user wishes. After placing the robot and positioning the goal, the program initiates the search. Once the goal is reached the program displays a message and waits for the user to press a key or the right mouse button before repeating the whole action with the same maze as before (see Fig. 14.3). The maze is randomly generated only the rst time the program starts. Throughout the program messages are displayed indicating what is happening. 14.1.1.1 MainProgram The MainProgram is self-documenting and requires no explanation. It also indicates the sequence of actions taken to accomplish the entire process. The variable FirstTime is used by the PlotMaze routine to determine whether to generate the maze or use the one previously generated. 14.1.1.2 DisplayInstructions This routine displays instructions to the user within a dialog box and then waits for a left mouse click on the OK or Cancel button or pressing the Enter or the Esc key. The subroutine makes use of the MsgBox() function. This function will return the key pressed (OK or Cancel) but no use is made of that information. Read about this function in the IDE help pages. 14.1.1.3 WaitForMouseOrKey As the name of the subroutine implies it waits for the user to press any key on the keyboard or the right mouse button. 14.1.1.4 PlotMaze This routine generates and plots the line maze. It creates a grid of junctions from which radiate a maximum of four lines. The combination of lines is
